FLAME-COVERING DEVICE.

Specification of Letters Patent.

Patented July 17, 1911*? Application filed March 13, 1917. Serial No. 154,498.

To all whom t may concern:

` Be it known that I, GEORGES G. Knns, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in Flame- Govering Devices, of which the following is a specification.

My invention'relates to a device adapted for use in connection with a gas operated stove, for covering the flames therein, and conducting the heated gases or products of combustion to the stack of the stove.

The invention aims to provide a device of the above mentioned character, which is of a simplified construction, and which will provide a uniform, dry, and non-scorching heat, to a broiler or griddle, arranged above or below the same.

Other objects and advantages of the construction will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specication and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of a stove, partly in section, showing my improved flame covering device in place therein,

Fig. 2 is a front face view of the stove, showing the device arranged therein, parts being shown in section,

Fig. 3 is a perspective view of the device embodying my invention,

Fig. 4 is a longitudinal 4sectional view taken on line 4 4; of Fig. 1, and,

Fig. 5 is a transverse sectional view taken on line 5 5 of Fig. 3.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates an oven of a gas stove. Disposed upon opposite sides of the oven 10 are gas burners 12, preferably of the siphon blast type. These burners 12 have horizontal tips 13, extending through openings 14, and discharging flames in a substantially horizontal direction within the oven 10. Arranged rearwardly of the oven is a stack or flue 15, discharging into the same between the tips 13.

My flame covering device comprises a central transverse tubular member 16, preferably triangular in cross section, with its base arranged lowermost. This transverse tubular member is closed upon its sides and bottom and its forward end 17 is closed, while its rear end is open and is placed into communication with the stack 15. Arranged upon opposite sides of the transverse tubular members 16 are longitudinal tubular members 18, which are preferably formed integral with the transverse member 16. The longitudinal members 18 are preferably triangular in cross section with their bases arranged lowermost. The longitudinal tubular members are closed upon their opposite sides while their bases are open. The inner ends of the longitudinal tubular members 18 are in communication with the interior of the transverse tubular member 16, while their outer' ends are connected by a transverse plate 19, covering the same, and having openings 20, for the reception of the burner tips 13.

In operation, with the device arranged as shown in Figs. 1 and 2, the burner tips 13 extending through the openings 20 and projecting into the longitudinal tubular members 18, the gas passing from the burner tips is ignited and the heated gases or products of combustion travel longitudinally through and inwardly of the longitudinal tubular members 18 and discharge into the transverse tubular member 16 and from thence into the stack 15. By having the base of the tubular members 18 open, suliicient air is supplied to the burner tips for proper combustion of the fuel, and the products of combustion are substantially retained within the longitudinal tubular mein-` bers by virtue of their tendency to rise therein.

I have found that by the use of this device, a uniform, dry, and non-scorching heat is provided, for the broiler or griddle, when arranged above or below the same.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. The combination with the oven of a stove, a stack arranged near the same, burners having burner tips projecting into y the` oven for providing suitable flames, longitudinal 'tubular members receiving the flames and products of combustion from the burner tips, and a transverse tubular member connected with the longitudinal tubular members and discharging into the stack.

2. The combination With the oven of a stove, of a stack arranged near the same, burners disposed upon opposite sides of ,the oven and having substantially horizontal tips projecting into the oven, longitudinal tubular members having their bottomsk open and adapted'to receive the flames and products of combustion fromV the burner tips, and atransverse tubular Vmember connecting the longitudinal tubular members and having its sides and base closed and one end thereof in communication With the stack.

3. A Vdevice of the character described, comprising a plurality of spaced longitudinal tubular members having their bottoms open, and a' transverse tubular member connecting the longitudinal tubular members and having its sides and base closed.

4. A device of the character described, comprising a plurality of spaced longitudinal tubular members which are substantially triangularin cross-section and have' GEORGES G. KREBS.
